STURBRIDGE, Mass., March 7, 2011 — Photonis USA has added a 40-mm size to its Gen2 ultrafast time-of-flight (TOF) detector product line, which now can support input areas from 18 to 40 mm and allows a TOF mass spectrometer to increase its mass resolution simply by replacing the detector.
The detector line addresses two major areas that affect resolution in TOF mass spectrometry: microchannel plate (MCP) flatness and anode spacing. The new detectors are equipped with proprietary and patented MountingPad microchannel plates to reduce anode spacing and use TruFlite MCP flatness technology for a significant reduction in time jitter. These technologies combine to produce a detector with high levels of detection sensitivity and good mass resolution.
The detectors provide typical pulse widths of <200 ps and a near-symmetric 120-ps rise and fall time. The TOF detectors offer built-in beam parallelism to provide uniform ion conversion and are designed for front flange mount.
